For Contractors New to Concrete Repair and Waterproofing

Find the correct Emecole Kit for the specific concrete repair problem below. Actual coverage may vary and is dependent on crack width, depth and the potential for enlarged voids further into the wall or slab.

Basement Wall Cracks - Wet & Leaking, Non-Structural

These cracks develop due to initial settling of the foundation or natural shrinkage of the concrete within a few months after being poured. These cracks tend to be thinner, anywhere from 1/8" to hairline. While they can occur anywhere in the foundation, they usually form around an opening, such as windows or doors. These cracks may be vertical or diagonal. These cracks allow in water and soil gases, including radon, which can affect the home's indoor air quality.

The low pressure injection of polyurethane properly fills cracks in the foundation and prevent further water entry. The Emecole Foundation Crack Repair Kit with Polyurethane Foam includes all the components necessary to repair either 10 foot or 30 foot cracks via low pressure injection.

When the foundation continues to move as a result of on-going settlement, soil pressure and freeze/thaw cycles, the end result is the formation of cracks. These cracks are more likely to be wider (gaps larger than 1/8" or more), horizontal, jagged or stair-stepped.

While basement wall cracks repaired via low pressure injection are strong and durable, the formation of new cracks around previously repaired cracks may develop as a result of actively moving foundations (i.e. continued soil settlement). In such scenarios, additional reinforcement beyond crack injection is necessary.

The installation of Carbon Fiber Staples distributes the stress load away from the damaged area, which prevents further crack formation. The Emecole Carbon Fiber Staple Crack Repair Kit includes everything needed for the proper installation of Carbon Fiber Staples into the basement wall.

Poured concrete walls that become bowed or have a significant amount of structural cracks need the rock solid reinforcement of Carbon Fiber Straps. The installation of Carbon Fiber Straps provides the tensile strength necessary to stabilize weak poured foundations or concrete block.

The Carbon Fiber Strap Kit includes all the components necessary for proper installation on the surface of the wall. For problem corner areas, we have specialized Carbon Fiber Corner Strap Kits for both poured foudnations and concrete block.

Typically, home builders drill holes into the foundation to accompany various basement sewer pipes or water lines. These holes are then sealed with a mortar or water plug. Since the voids still exist, water comes in and eventually overtakes the sealed area resulting in leakage. These voids also provide an entry for soil gases, including radon.

Leaking pools and the loss of water are often the result of cracks on the pool's poured concrete wall. Pool cracks usually occur as a result of ground movement, freeze/thaw cycles, inadequate bearing of soil or a lack of or improper placement of reinforcing steel.

The Emecole Pool Bond Repair Kit includes the materials needed to properly fill cracks in poured concrete pool walls via low pressure injection. The proper filling of these cracks will ensure that the crack is completely filled and will no longer leak water.

Indoor Concrete Floor Cracks (Basements or Garages)

Cracks in basement floors and garage floors usually occur as a result of concrete shrinkage, a poor mixture of concrete and water, poor installation methods or a combination of all of the above. These cracks can seep in water and provide an entry for dangerous soil gases, including radon.

The Emecole Slab Crack Repair Kit provides the components necessary to fill cracks in basement and garage floors. The repaired area is fused together, resulting in a strengthened surface that is strong and durable.

Cracks in recently poured concrete occur naturally due to the shrinkage of concrete, which unfortunately leaves driveways, patios, sidewalks and pool decks vulnerable to cracking. In older concrete flat surfaces, cracks may form as a result of a poorly installed base, freeze-thaw cycles or pressure from soil or tree roots.

When freeze-thaw cycles or expansion/contraction of concrete result in the widening of previously thin concrete cracks, this is a sign that active movement exists (cracks larger than 1/8" gap or wider). Such floor crack repairs require additional reinforcement to minimize the formation of new cracks around previously repaired cracks.

Following the repair of a crack in a concrete floor or slab, the installation of Carbon Fiber Stitching Dogs will protect the repaired area from the formation of new cracks due to movement in the concrete. The Emecole Carbon Fiber Stitching Dog Accessory Kit includes everything needed for proper Stitching Dog installation.

Open control joints in concrete floors can cause problems in warehouses in which forklifts are used. The Emecole Control Joint Filler Kit provides the components necessary to fill control joints in any concrete floor or slab surface.
